Hi Japo,
Not really sure what has happened here as this thread was marked resolved but I can no longer see the replies that were made to my thread and I have also lost some PMs related to this thread.
This appears to have been a permissions problem for the limited user account and is resolved in that respect. I had difficulty finding the BOC426 folder but thanks to Red and another moderator (post from second mod is gone, Red kindly sent a PM), I located the folder in question.
I have been using BOClean for a long time and always shut down then uninstall the old version then install the new version but this did not help with the permissions problem.
With help from Red I realized I failed to check the box to search for hidden files and folders which is why BOC426 did not show up in my search.
Thank you so much for your reply but all appears well now, except for the missing posts in this thread
